The Hancock Jaffe Surgical Antireflux Venous Valve Endoprosthesis (SAVVE) Study

A prospective, non blinded, single arm, multicenter study designed to assess the safety and effectiveness of the bioprosthetic, VenoValve, which is surgically implanted into the deep venous system for treatment of patients with deep venous valvular insufficiency ( C4b-C6 patients).

The purpose of this study is to evaluate the VenoValve System (Hancock Jaffe Laboratories) in human patients. The VenoValve System is designed for treatment of chronic deep venous insufficiency. The VenoValve System enables improvement in chronic lower extremity venous reflux through an open surgical technique. The objective of this study is to assess the safety and effectiveness of the VenoValve System for the treatment of patients with deep venous valvular insufficiency and the associated complications.
